Ive sent out 2 links that should be worth a read - more so for the Exchange
Admin guru :-)

stopped brick level several years ago (when recov mgr was by aelita).  if
you have the tape tech to handle a few steams that may be of value to you or
use a disk target.  is there any regulatory/compliance/business req that you
have no choice but to keep doing it?

also, is your exch info store 1 big store or is it broken up into a few db's
or split among a few servers?

 
aaarrrggghhh!!!!

Im also running Ex2K3 and have about 900 mailboxes. The slowness is killing
my backup window since it takes 11 hours. I'm looking into Quest Recovery
Manger now. So you don't use NBU for your mailboxes at all??
 
Also should I be running multistreaming?

for a single stream for mb's your doing well.  consider alt routes for
mailbox/message recovery.  the tools with exch may be of value (if you are
2003 or greater).  the quest recov mgr  for exch (keep hawking it, used it
to recover 8 mailboxes yesterday and several last week) has been great,
wasnt too expansive (we have 1000 mailboxes).  im sure others may have
suggestions as well.

your time range is what we were hitting when we were on 5.5 and we have now
increased db size and exch serv count by 500%, so im glad we stopped with
brick level exch jobs.

Well first of all data is located on the local exchange machine. Backups are
running on gigabit Ethernet and the max KBps I get is around 6400. The
policy setup is using MS Exchange and I selected MS EXCHANGE MAILBOX from
the directives set. I don't know what recovery storage groups are since im
not responsible for exchange and if my exchange guy knew about it he
should've told me bit I guess he doesn't. what can I do with that? 
 
Currently I have no SAN. We are still in the process of evaluating what we
need. It takes almost 11 hours to backup my full mailbox store. Info_Store
backups are fast at around 40MBps. I have no mutliplexing/multistreaming
configured on this policy. Would it make a difference for exchange? If so,
what should the settings be given I have a Hp MSL6060 Tape Lib with to LTO3
drives?

Well that makes more sense, because I have never, ever seen any performance
increase of BLB regardless of the hardware involved, the spindles involved,
fiber, tape technology. And the originator was specifically asking about the
backup type "BLB".
 
BLB are slow, slow slow! and should be avoided - as I pointed out in an
earlier thread, Ex2k3 offers ALOT more functionaility for you to move away
from this type of backup.

I'd tell you I've got the magic voodoo over here Paul, but then you'd want
it.  And If I'm gonna give up the goods I'd better get dinner and dancing
first. =P
 
Our Exchange Fulls running by themselves over GigE to a DSSU sitting around
doing nothing else does about 100MB/sec, until it hits the logs.  Even then,
its very fast but the average time rounds out to 80MB/sec, still
respectable.  My fastest backup until that point was a Redhat 3 /  Oracle 9
Database at 55MB/sec (give or take Archive logs.)  In my Exchange case, the
secret has been number of spindles and drive speeds on the SAN.  We did
serious I/O testing on the Exchange server's storage and went for
performance all the way.  I think each storage group and logs are their own
8 disk raid5 w/ 146GB 15K FC drives in a Hitatchi SAN.  Surprisingly, I got
a Sun StorEdge 5320 running remote NDMP backups to LTO3 at 100MB/sec first
try, yesterday!  That was purely test data, and it remains to be seen if it
will maintain that after we load up terabytes of data.  (I don't manage the
SAN or the NAS, so all my secret sauce is definitely someone else's.)
 
I haven't done a brick level backup of Exchange since I learned about
Recovery Storage Groups, and that was on Arcserve, or whatever it was called
before CA bought it.  That was the 90's and all my memories from the 90's
are bad, so lets not go there.  I have to admit I've never run BSD.  Sounds
like fun, and the devil logo has definitely got it going on!  Silly penguin.

I've never seen 100MB/s, let alone "better than" 100MB/s on a single GigE
link, for ANY client type, let alone Windows, or Exchange, so colour me
surprised.

you are seeing this speed doing brick level, or are you seeing it with info
store backups?  ive never seen brick level go too fast on any type of
disk/net/tape drive combo (5.5/2000/2003).  info stores go quite fast in all
cases (as expected).
